The increase in available electricity follows weekend meetings with Eskom at which Implats said it has agreed to assist in reducing mining industry demand for power by 10%.

Mining operations at Rustenburg have been halted since Friday due to a shortage of generating capacity at Eskom.

Implats reiterated that the impact on production is in the order of 3,500 ounces of platinum a day and said its refining operation is receiving reduced input from suppliers similarly affected by power shortages.

"The company remains in communication with Eskom and will attend a meeting with them tomorrow (Tuesday) morning to discuss the further ramp up of operations," the Johannesburg-based company said.

It added the full production and the financial impact will be estimated and communicated as soon as possible.

the global platinum numbers one and three, have also been forced to suspend mining operations in South Africa after Eskom last Friday said it couldn't guarantee the supply of electricity. Gold producers and other miners have been similarly affected.

Several companies Monday said they had begun receiving further supplies of power from Eskom, allowing them to resume underground maintenance of mines in readiness for a return to normal output.
